| CVE-2026-73046 | 2026-08-26 | N/A | 9.8 CRITICAL | ||
| SiYuan before v3.7.4 improperly restricts excessive authentication attempts in the CheckAuth() middleware. The HTTP Basic Authentication branch, which guards nearly the entire /api/* surface, accepts the workspace access code (Conf.AccessAuthCode) as the Basic Auth password but never consults the CAPTCHA/lockout gate or increments the failure counter used by the cookie/session login path. This allows unauthenticated remote attackers to brute-force the admin access code with unlimited automated requests and obtain full RoleAdministrator access to the kernel. A secondary weakness exists because the access code is compared using a non-constant-time string comparison. | |||||
| CVE-2026-73056 | 2026-08-26 | N/A | 9.8 CRITICAL | ||
| SiYuan kernel versions before 3.7.4 contain an improper restriction of excessive authentication attempts vulnerability in the CheckAuth() middleware. The middleware accepts the API token (Conf.Api.Token) via an Authorization header (Token/Bearer) or a ?token= query parameter, and neither path is protected by the application's CAPTCHA/lockout mechanism (NeedCaptcha/WrongAuthCount). As a result, an unauthenticated remote attacker can perform unlimited automated guesses of the API token, particularly when a short or weak custom token has been configured, and upon success gains full RoleAdministrator access enabling arbitrary file operations and SQL queries. | |||||
| CVE-2026-73045 | 2026-08-26 | N/A | 7.5 HIGH | ||
| SiYuan before 3.7.4 contains an improper restriction of excessive authentication attempts vulnerability in the authFilePublishAccess endpoint that allows unauthenticated attackers to brute-force per-notebook publish passwords. Attackers can submit unbounded password guesses without rate limiting or CAPTCHA to gain access to password-protected published notebooks. | |||||
| CVE-2026-74868 | 2026-08-26 | N/A | 7.5 HIGH | ||
| SiYuan versions before 3.7.4 contain an unthrottled brute-force vulnerability in the Publish Service Basic Auth implementation (PublishServiceTransport.RoundTrip() in kernel/server/proxy/publish.go). The Publish Service runs on a separate, unauthenticated-by-default listener (default TCP port 6808) and gates named publish-viewer accounts (Conf.Publish.Auth.Accounts) with Basic Auth that has no rate limiting, per-account lockout, or backoff. Unauthenticated remote attackers can submit unlimited password guesses against named accounts to gain access to published notes/notebooks. | |||||
| CVE-2026-16619 | 2026-08-26 | N/A | 7.5 HIGH | ||
| The miniOrange 2FA WordPress plugin before 6.2.8 does not correctly limit the number of second-factor verification attempts, tracking them against a client-supplied identifier that is reissued on every login, allowing an attacker who already knows a user's password to guess the one-time code without limit and take over the account. | |||||

| CVE-2023-21709 | 1 Microsoft | 1 Exchange Server | 2026-08-10 | N/A | 9.8 CRITICAL |
| Microsoft Exchange Server Elevation of Privilege Vulnerability | |||||
| CVE-2026-15144 | 1 Fastify | 1 Fastify\/rate-limit | 2026-08-05 | N/A | 7.3 HIGH |
| @fastify/rate-limit before 11.2.0 keys rate-limit buckets by the verbatim client IP string returned from request.ip. Because a single IPv6 client can control a large address range (a /64 holds 2^64 distinct addresses) and the same address has multiple valid textual representations, an IPv6 capable client can defeat the rate-limit boundary by rotating addresses or by rewriting the same address in different forms. Applications that use @fastify/rate-limit to protect endpoints such as authentication, password reset, OTP delivery, or expensive API calls can be bypassed by IPv6 clients behind a proxy that surfaces IPv6 to the origin when trustProxy is enabled. The issue is fixed in @fastify/rate-limit 11.2.0, where the default key generator normalizes IPv6 addresses to their canonical form, collapses IPv4 mapped IPv6 to IPv4, and applies a configurable prefix mask (default /64) via a new ipv6Subnet option. | |||||
| CVE-2026-16347 | 2026-07-30 | N/A | 8.8 HIGH | ||
| MikroTik RouterOS contains a weakness in its API authentication handling that lacks effective safeguards against excessive login attempts. The system does not enforce meaningful rate-limiting, account lockout, or source-based restrictions, allowing repeated authentication failures to proceed without defensive response. In some versions, a fixed per-connection delay is present, but it can be bypassed through concurrent sessions, resulting in continued high-volume attempts. This deficiency increases the risk that an attacker could eventually obtain valid credentials and gain unauthorized access to administrative services. | |||||
| CVE-2021-29023 | 1 Invoiceplane | 1 Invoiceplane | 2026-07-29 | 5.0 MEDIUM | 5.3 MEDIUM |
| InvoicePlane 1.5.11 doesn't have any rate-limiting for password reset and the reset token is generated using a weak mechanism that is predictable. | |||||
| CVE-2025-36363 | 1 Hcltech | 1 Devops Plan | 2026-07-27 | N/A | 5.9 MEDIUM |
| IBM DevOps Plan 3.0.0 through 3.0.5 uses an inadequate account lockout setting that could allow a remote attacker to brute force account credentials. | |||||
| CVE-2026-34505 | 1 Openclaw | 1 Openclaw | 2026-07-24 | N/A | 6.5 MEDIUM |
| OpenClaw before 2026.3.12 applies rate limiting only after successful webhook authentication, allowing attackers to bypass rate limits and brute-force webhook secrets. Attackers can submit repeated authentication requests with invalid secrets without triggering rate limit responses, enabling systematic secret guessing and subsequent forged webhook submission. | |||||
| CVE-2026-33580 | 1 Openclaw | 1 Openclaw | 2026-07-24 | N/A | 6.5 MEDIUM |
| OpenClaw before 2026.3.28 contains a missing rate limiting vulnerability in the Nextcloud Talk webhook authentication that allows attackers to brute-force weak shared secrets. Attackers who can reach the webhook endpoint can exploit this to forge inbound webhook events by repeatedly attempting authentication without throttling. | |||||
| CVE-2026-41893 | 1 Signalk | 1 Signal K Server | 2026-07-24 | N/A | 7.5 HIGH |
| Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.25.0, the HTTP login endpoints (POST /login and POST /signalk/v1/auth/login) are protected by express-rate-limit (default: 100 attempts per 10-minute window, configurable via HTTP_RATE_LIMITS). The WebSocket login path — sending {login: {username, password}} messages over an established WebSocket connection — calls app.securityStrategy.login() directly without any rate limiting. An attacker can bypass HTTP rate limiting entirely by opening a WebSocket connection and attempting unlimited password guesses at the speed bcrypt allows (~20 attempts/sec with 10 salt rounds). This issue has been patched in version 2.25.0. | |||||
| CVE-2026-1816 | 2026-07-23 | N/A | 6.3 MEDIUM | ||
| Improper restriction of excessive authentication attempts vulnerability in Turkiye Electricity Transmission Corporation (TEİAŞ) Mobile Application allows Brute Force. This issue affects Mobile Application: from 1.6.2 before 1.13. | |||||
| CVE-2026-43926 | 2026-07-22 | N/A | N/A | ||
| FOSSBilling is a free, open-source billing and client management system. Prior to version 0.8.0, the password reset confirmation endpoint `/client/reset-password-confirm/:hash` is handled by a non-API controller and is not covered by FOSSBilling's rate limiter, which only applies to `/api/*` routes. This allows an attacker to probe the endpoint for valid reset tokens without any per-IP request limiting, attempt counting, or lockout mechanism. The endpoint acts as an oracle, returning a distinguishable response for valid versus invalid tokens (HTTP 200 vs HTTP 302 redirect). An attacker can submit unlimited token guesses to the password reset confirmation endpoint with no throttling applied. However, practical exploitability is significantly mitigated by the current token generation, which uses `hash('sha256', random_bytes(32))`, providing 256 bits of entropy. Tokens also expire after 15 minutes and are deleted after successful use. The same architectural gap applies to other controller-served auth routes, including `/staff/email/:hash` (admin password reset confirmation) and `/client/confirm-email/:hash` (email confirmation). Version 0.8.0 fixes the issue. Some workarounds are available. Configure a reverse proxy (e.g., Nginx, Apache, Cloudflare) to apply per-IP rate limiting to the `/client/reset-password-confirm/*` and `/staff/email/*` paths and/or use a WAF rule to limit request rates to these endpoints. | |||||
| CVE-2026-36607 | 2026-07-22 | N/A | 8.8 HIGH | ||
| Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 allows unauthenticated brute-force attacks via the TDDP password change endpoint (code=10), which lacks the rate limiting applied to the login endpoint (code=7). An attacker on the adjacent network can attempt unlimited passwords without triggering account lockout. | |||||
